An NYPD cop was busted by the FBI on Friday in an alleged murder-for-hire plot that targeted her estranged husband, law enforcement sources said Friday.

Officer Valerie Cincinelli, 34, is accused of using her boyfriend to hire a hit man in the failed scheme, according to a source familiar with the matter.

Cincinelli, who was hired in 2007, was a domestic-violence officer assigned to the 106th Precinct in Queens when she became involved with a local man she met on the job, a source said.

She was stripped of her badge and gun in 2017 after she ended the relationship and the man told the Internal Affairs Bureau that Cincinelli had spent time at his Howard Beach home while on duty, the source said.

It’s unclear if that man — who was described as an older “sugar daddy” who paid for Cincinelli’s car and other bills — is the same one in the alleged murder-for-hire plot.

Cincinelli’s husband, Isaiah Carvalho Jr., sued her for divorce in Nassau County Supreme Court last year, with a trial set for June, court records show.

When reached by phone Friday, Carvalho said, “You gotta give me some time. I can’t talk about this right now.”
